Description

Technical Field

[0001] This application relates to the field of surveillance mounting bracket technology, and in particular to a lightning protection and wind resistance mounting device for power plant video surveillance. Background Technology

[0002] In power plant safety management, video surveillance systems play a crucial role. However, the complex environment of power plants and the fact that surveillance equipment is often installed high on exposed walls pose two major challenges: lightning strikes and damage from strong winds.

[0003] The existing video surveillance installation devices mostly use cantilever beam fixed structures for their mounting poles. The support strength is determined during installation. When encountering strong winds exceeding the design value, the pole is prone to violent shaking or even bending and deformation, resulting in blurred camera images and positioning failure. In severe cases, it can cause the pole to tilt and damage the equipment. This static and passive wind resistance mode cannot adapt to the ever-changing natural wind force. Utility Model Content

[0004] To address the issues of passive and unstable wind resistance of installation poles, this application provides a lightning protection and wind resistance installation device for power plant video surveillance.

[0005] The lightning protection and wind resistance installation device for power plant video surveillance provided in this application adopts the following technical solution:

[0006] A lightning protection and wind resistance installation device for power plant video surveillance includes an installation plate, a main pole on the installation plate, a secondary pole slidably disposed within the main pole and bolted to the installation plate to provide a stable foundation, a monitoring camera fixedly mounted on the secondary pole, a lightning protection device mounted on the monitoring camera, and an auxiliary component for adaptive wind resistance within the installation plate. The movable end of the auxiliary component is provided with four support rods that form a triangular stable structure through movement.

[0007] By adopting the above technical solutions, the mounting plate provides a stable installation foundation for the entire device, the sliding connection between the main rod and the auxiliary rod realizes the rigid support of the camera, the lightning protection device provides lightning protection for the camera, and the auxiliary components form an adaptive triangular stabilizing structure by driving the support rod, which together realizes the dynamic stability and safety protection of the device in strong wind and thunderstorm environments.

[0008] Preferably, the main rod is fixedly provided with a diagonal rod that is fixedly connected to the mounting plate.

[0009] By adopting the above technical solution, its small-angle tilt design is firmly connected with the main pole and the mounting plate, forming a stable triangular support, which effectively improves the bending and overturning resistance of the main pole, thereby enhancing the foundation stability of the entire installation device.

[0010] Preferably, the secondary rod is square in shape, and the inner wall dimensions of the main rod are adapted to the dimensions of the secondary rod.

[0011] By adopting the above technical solution, this cooperative relationship ensures that the auxiliary pole can only slide vertically inside the main pole and cannot rotate, preventing the camera from deviating from the monitoring position due to accidental twisting, while ensuring the stability of the support force transmission.

[0012] Preferably, the auxiliary component includes a threaded rod rotatably disposed with the main rod, a servo motor fixedly disposed inside the main rod, the drive end of the servo motor being fixed to the threaded rod, a circular sleeve threaded on the threaded rod and slidably connected to the main rod, four first sliding grooves extending into the interior of the auxiliary rod being formed in a circumferential array inside the main rod, an extension groove penetrating the auxiliary rod being formed in the first sliding groove, four first sliding plates sliding in the first sliding groove and the extension groove being formed in a circumferential array on the circular sleeve, the end of the first sliding plate away from the circular sleeve being hinged to a support rod, and the support rod covering and extending the moving distance of the support rod through a moving structure.

[0013] By adopting the above technical solution, the servo motor drives the threaded rod to rotate, which in turn drives the ring sleeve and the first slide plate to move in a precise linear motion along the first slide groove and the extension groove. This converts the rotational power of the motor into the driving force for the support rod to unfold or retract, thereby realizing the automatic deployment and retraction of the wind-resistant structure.

[0014] Preferably, the movable structure includes four second sliding grooves arranged in a circumferential array on the mounting plate, wherein two of the second sliding grooves are provided with a first through groove, and the other two second sliding grooves are provided with a second through groove. Second sliders hinged to the support rod are slidably arranged in the four second sliding grooves, wherein two of the second sliders are fixedly provided with a sleeve plate, and the other two second sliders are fixedly provided with an insert plate that is slidably arranged with the sleeve plate.

[0015] By adopting the above technical solution, the sliding of the second slider in the second groove provides a moving track for the bottom of the support rod. The telescopic protective structure formed by the staggered sleeve plates and insert plates not only greatly extends the effective moving distance of the bottom of the support rod, but also covers the groove opening throughout, effectively preventing the jamming problem caused by the intrusion of external debris.

[0016] Preferably, the dimensions of the second groove are adapted to the dimensions of the sleeve plate and the insert plate.

[0017] By adopting the above technical solution, it is ensured that the sleeve plate and the insert plate can slide tightly and smoothly in the slide groove, which not only ensures the movement accuracy of the telescopic protection mechanism, but also avoids the protection failure due to excessive gap or jamming due to insufficient gap.

[0018] Preferably, the positions of the first through groove and the second through groove are staggered, and their extension lines are perpendicular to each other.

[0019] By adopting the above technical solution, the spatial layout of the movement path at the bottom of the four support rods is optimized to avoid interference between the drive mechanisms of adjacent support rods during movement, and to ensure that all support rods can be deployed and retracted synchronously and smoothly.

[0020] Preferably, the dimensions of the extension groove are adapted to the dimensions of the support rod.

[0021] By adopting the above technical solution, a smooth channel is provided for the entire movement process of the support rod from the retracted state to the fully extended state, ensuring that the support rod can pass smoothly through the secondary rod structure, thereby completing the stable form transformation from vertical storage to inclined support.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The plug-in structure of the main pole and auxiliary components facilitates installation and maintenance. Combined with the small-angle diagonal brace at the bottom of the main pole, it provides a reliable foundation for the system. The wind speed sensor monitors the ambient wind force in real time. When the wind force increases, the system automatically starts the servo motor to change the four support poles from a retracted state to an inclined support state. Each support pole forms a triangle with the mounting plate and the main pole, transforming the mechanical model of the main pole from a dangerous cantilever beam to an extremely stable spatial frame. This transformation from static to dynamic allows the device to remain compact in calm weather and obtain maximum support rigidity and anti-tipping ability during storms, effectively suppressing pole swaying and ensuring clear and stable images.

[0024] 2. The design of the sleeve plate and insert plate solves the reliability and travel problem of the moving parts. It not only effectively extends the movement distance of the second slider without increasing the physical size of the mounting plate, but also allows the support rod to achieve a better tilt angle and form a larger support surface. More importantly, this design always covers the empty part of the second slider, reducing the probability of dust and other impurities clogging the second slide groove. Attached Figure Description

[0034] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0035] This application discloses a lightning protection and wind resistance installation device for power plant video surveillance.

[0036] Reference Figures 1 to 4 A lightning protection and wind resistance installation device for power plant video surveillance includes an installation plate 1. A main rod 4 is set at the center of the installation plate 1. A secondary rod 5 is slidably set inside the main rod 4. The secondary rod 5 is bolted to the installation plate 1 to provide a stable foundation. A monitoring camera 2 is fixedly set at the end of the secondary rod 5 away from the installation plate 1. A lightning protection device 3 is set on the monitoring camera 2. A wind speed sensor (not shown in the figure) is also installed on the top of the monitoring camera 2. An auxiliary component 6 is set inside the installation plate 1. The auxiliary component 6 is used to realize the self-adaptation of wind resistance. Four support rods 7 are set at the moving end of the auxiliary component 6. The four support rods 7 form a triangular stable structure by moving. A diagonal rod 41 is fixedly set on the main rod 4. The diagonal rod 41 is fixedly connected to the installation plate 1 and is set between the main rod 4 and the installation plate 1. The secondary rod 5 is square in shape, and the inner wall dimension of the main rod 4 is also square, which is compatible with the square dimension of the secondary rod 5.

[0037] The lightning protection device 3 includes a Class II surge protector (SPD) and a video signal surge protector. The surge protector and video signal surge protector are mounted on top of the base of the surveillance camera 2 and connected in series to the power and signal lines of the surveillance camera 2. The mounting plate 1, main rod 4, auxiliary rod 5, and support rod 7 are all connected by metal conductive connections. A dedicated grounding terminal (not shown) is provided on the mounting plate 1. This grounding terminal has a grounding depth of not less than 16mm. 2The grounding cable is reliably equipotentially connected to the power plant's grounding grid to ensure that lightning current can be safely discharged into the ground.

[0038] When there is no wind or the wind is light, the device is in standby and stored state: the auxiliary rod 5 is inserted into the main rod 4 and fixed to the mounting plate 1 at the bottom with bolts, forming a compact whole structure. The monitoring camera 2 performs normal monitoring, and the lightning protection device 3 at the top continuously provides lightning protection. At this time, the auxiliary component 6 is not activated, and the support rod 7 is in the retracted position and does not form support. The entire device relies on the plug-in structure of the main rod 4 and the auxiliary rod 5, as well as the small-angle diagonal rod 41 fixed to the mounting plate 1 at the bottom of the main rod 4 to provide the stability of the foundation. The tight fit between the square auxiliary rod 5 and the inner wall of the main rod 4 effectively prevents the monitoring camera 2 from twisting under the action of wind or external force. During most periods without strong wind, the device maintains a streamlined shape, which greatly reduces the normal wind load. This avoids the main rod 4 and the auxiliary rod 5 bearing unnecessary stress for a long time, significantly reduces material fatigue, and extends the service life of the entire device.

[0039] Reference Figures 3 to 5 The auxiliary component 6 includes a threaded rod 61 rotatably disposed with the main rod 4. The threaded rod 61 is located inside the main rod 4. A servo motor 63 is fixedly disposed at one end of the main rod 4 near the mounting plate 1. The mounting end of the servo motor 63 is fixed to the inner wall of the main rod 4. The driving end of the servo motor 63 is fixed to the threaded rod 61 through a coupling. A circular ring sleeve 62 is threaded on the outer wall of the threaded rod 61. The circular ring sleeve 62 is slidably connected to the inner wall of the main rod 4 and is sized to match. The threaded rod 61 is a small lead ball screw with transmission self-locking, and the circular ring sleeve 62 is the nut of the ball screw.

[0040] The inner wall of the main rod 4 has four first sliding grooves 64, which extend into the interior of the secondary rod 5 but do not penetrate through it. The four first sliding grooves 64 are arranged in a circumferential array inside the main rod 4. An extension groove 66 is provided on the side of the first sliding groove 64 near the mounting plate 1. The extension groove 66 penetrates through the interior of the secondary rod 5. Four first sliding plates 65 are fixedly installed on the outer wall of the annular sleeve 62. The four first sliding plates 65 are arranged in a circumferential array corresponding to the positions of the first sliding grooves 64. The first sliding plates 65 slide on the inner walls of the first sliding grooves 64 and the extension grooves 66, and their sizes are compatible. The first sliding plates 65 are hinged to the support rod 7. The support rod 7 is located at the end of the first sliding plate 65 away from the annular sleeve 62. The support rod 7 covers and extends the movement distance of the support rod 7 through a moving structure. The size of the extension groove 66 is compatible with the size of the support rod 7, and is used to accommodate the support rod 7 to enter the extension groove 66 and extend the movement distance.

[0041] When the wind speed sensor detects that the wind force exceeds the set threshold, the wind-resistant mode is activated: the servo motor 63 located in the main rod 4 starts, driving the threaded rod 61 to rotate. The annular sleeve 62, which is threaded with the threaded rod 61, moves upward or downward under the action of rotation, causing the four first sliding plates 65 in the upper ring array to slide synchronously along the first sliding groove 64 and extension groove 66 on the main rod 4 and the secondary rod 5. The movement of the first sliding plate 65 then pushes the upper end of the support rod 7 that is hinged to it, forcing the support rod 7 to start tilting outward from the retracted state. The size of the extension groove 66 is adapted to the support rod 7, ensuring that the support rod 7 can pass smoothly through the structure of the secondary rod 5 during the movement, preparing for the formation of large-angle support.

[0042] Reference Figures 4 to 7 The movable structure includes four second sliding grooves 67 arranged in a circumferential array on the mounting plate 1. Two of the second sliding grooves 67 have first through grooves 68, which are relatively parallel to each other. The first through grooves 68 penetrate the interior of two of the second sliding grooves 67. The other two second sliding grooves 67 have second through grooves 69, which are also relatively parallel to each other. The second through grooves 69 also penetrate the interior of the other two second sliding grooves 67. Second sliders 610 are slidably arranged in the four second sliding grooves 67. The bottom dimension of the second sliding groove 67 is larger than the opening dimension of the second sliding groove 67. The cross-section of the second sliding groove 67 is convex. The size of the second slider 610 is adapted to the size of the second sliding groove 67. The end of the support rod 7 away from the main rod 4 is hinged to the second slider 610.

[0043] Two adjacent second sliders 610 are fixedly provided with sleeve plates 611, and two other adjacent second sliders 610 are fixedly provided with insert plates 612. The outer wall of the insert plate 612 is slidably disposed with the inner side of the sleeve plate 611. The size of the second slide groove 67 is adapted to the size of the sleeve plate 611 and the insert plate 612 to prevent impurities from entering the internal gap of the second slide groove 67. The positions of the first through groove 68 and the second through groove 69 are staggered. The first through groove 68 and the second through groove 69 slide with the sleeve plate 611 respectively, and the extension lines of the first through groove 68 and the second through groove 69 are perpendicular to each other.

[0044] As the upper end of the support rod 7 is pushed by the first sliding plate 65, its bottom also begins to move. The bottom end of the support rod 7 drives the second slider 610, which is hinged to it, to slide within the second groove 67 on the mounting plate 1. In order to extend the sliding distance and prevent the groove opening from being exposed for a long time, the sleeve plate 611 and the insert plate 612, which are fixed to the second slider 610, move accordingly. The two together form a retractable protective cover. This design allows the second slider 610 to move a long distance without exposing the inside of the second groove 67, effectively preventing dust, rainwater and other debris from entering and causing blockage. The staggered vertical design of the first through groove 68 and the second through groove 69 provides an independent channel for the movement path of the bottom of the adjacent support rods 7, avoiding movement interference. Finally, the four support rods 7 are fully extended, forming a large and stable triangular support structure with the mounting plate 1 and the main rod 4, which greatly enhances the anti-overturning ability of the entire device in strong winds. When the wind weakens, the servo motor 63 rotates in the opposite direction, driving all components to move in the opposite direction according to the above process, causing the support rods 7 to retract and the device to return to normal.

[0045] The mounting plate 1 is made of Q345B steel plate with hot-dip galvanizing for corrosion protection. The main rod 4 is made of 6061-T6 aluminum alloy profile with anodized finish. The auxiliary rod 5 is made of aluminum alloy square tubing to ensure sliding fit with the inner wall of the main rod 4. The four support rods 7 are made of 6061-T6 aluminum alloy profile to ensure high compressive strength while maintaining lightweight. The wind speed sensor is a three-cup anemometer.

[0046] Among them, the monitoring camera 2, the lightning protection device 3, and the servo motor 63 are existing technologies, and their structural principles will not be described in detail. The system is powered by an external power supply. After the power line is connected to the device, it first undergoes primary protection through the lightning protection device 3. The power supply is then divided into two paths: one path provides stable power to the monitoring camera 2, and the other path is connected to the control system (usually a programmable logic controller). The signal output terminal of the wind speed sensor is connected to the control system to monitor the ambient wind force in real time. When the wind speed sensor detects that the wind force exceeds the preset threshold, it sends a signal to the control system. The control system then starts the servo motor 63, driving the threaded rod 61 to rotate. The rotation of the threaded rod 61 is converted into the linear motion of the ring sleeve 62, which in turn pushes the top of the four support rods 7 through the first sliding plate 65, causing their bottoms to slide in the second sliding groove 67 through the second slider 610. Finally, the support rods 7 unfold from the folded state into a stable triangular structure. When the wind force weakens, the control system commands the servo motor 63 to reverse, so that the support rods 7 can be smoothly folded back to normal.

[0047] The implementation principle of a lightning protection and wind resistance installation device for power plant video surveillance in this application embodiment is as follows: When there is no wind or the wind force is small, the device is in a standby storage state: the auxiliary rod 5 is inserted into the interior of the main rod 4, the square auxiliary rod 5 is tightly fitted with the inner wall of the main rod 4, and is fixed to the bottom mounting plate 1 by bolts to form a compact overall structure. The monitoring camera 2 performs normal monitoring, and the lightning protection device 3 at the top continuously provides lightning protection. At this time, the auxiliary component 6 is not activated, the support rod 7 is in the retracted position and does not form support, and the ambient wind force is monitored in real time by the wind speed sensor.

[0048] When the wind increases, the system automatically activates the auxiliary component 6, changing the four support rods 7 from a retracted state to an inclined support state. This transforms the mechanical model of the main rod 4 from a dangerous cantilever beam to an extremely stable spatial triangular truss. This transformation from static to dynamic allows the device to remain compact in calm weather and achieve maximum support rigidity and anti-tipping ability when a storm arrives, effectively suppressing the swaying of the rods and ensuring a clear and stable image.

[0049] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
